We stayed at this place for a bit over a week and really enjoyed the quiet, very well organized space. The apartment is very close (about 7 mins walk) to Wongsawang station (Purple line of MRT), yet you never hear any rail noise in the apartment itself which faces the other direction and is located on the 13th floor. There is a 7/11 within a couple minutes of walk and a proper grocery store (BigC) and small mall within 10 mins walk.
The gym and swimming pool which are both located in the facility building next door are both clean, spacious and rather empty most of the time, making you feel like you've go the whole place to yourself. There is also a movie room, a kids' playroom and a nice rooftop garden on the top floor of the main building.
If you don't mind being a bit out of the center of Bangkok, this is a great place to stay at. We preferred being here and then taking the MRT/BTS to wherever else we wanted to visit. It was nice to come back in the evenings and unwind with a swim in the spacious pool.
The apartment itself is just as shown in the pictures - everything is clean and well-organized. We even found a sewing kit, first aid kit and pool bags with towels for our use in the bedroom closet! The hosts have clearly put in a lot of thought into this place. They also provide a Guide book which is really handy and explained everything plus provided emergency phone numbers. The Smart TV was great for watching Netflix and the kitchen had everything we needed.
When we had a small issue with the kitchen drain, Thittaya responded immediately and was very quick to fix it. Overall, the communication was really great and we thoroughly enjoyed our stay at this neat little apartment and would certainly come back if we visit Bangkok again.
